摘要： A method for providing instant replay is disclosed. According to the method, a video stream and an audio stream are received from a source. A program is rendered from the video and audio streams and played in real time. The video stream and the audio stream are compressed using a video compression engine and an audio compression engine respectively. Information relating to the compressed video and audio streams and the video and audio compression engines is stored in a sequence header. The compressed video and audio streams are multiplexed to form a single data stream. The information relating to video and audio frames including synchronization information is stored in a multiplexer header. Media units are formed from the multiplexed data stream. Each media unit includes at least one video frame and at least one or more corresponding audio frames. Each media unit further includes a first video frame that is independently decodable. Each media unit is an independently decodable entity. The media units have a fixed duration. The media units are stored in a memory. A number of starting addresses are stored in a table. Each of the starting addresses corresponds to one of the media units. The sequence header is retrieved in response to receipt of an instant replay command. Appropriate video and audio decompression engines are selected and configured based on the retrieved sequence header. An instant replay starting address is identified from the table in response to receipt of the instant replay command. One or more media units are retrieved from the memory starting with the media unit associated with the instant replay starting address. The one or more retrieved media units are demultiplexed into compressed video and audio data for respective delivery to the video and audio decompression engines. The decompressed data are then rendered.

摘要： The present invention describes a decentralized symmetric configuration of digital video recorders (DVCRs) for monitoring, controlling, analyzing, recording, playback and streaming of audio/visual (A/V) media over a network. Each DVCR is an autonomous device able to operate in its local environment as well as access and operate another DVCR available on the network to facilitate the overall working of the disclosed system. Each DVCR also exhibits storage fail-safe feature whereby it recovers data automatically if storage media gets corrupted such as due to sudden power failure. A DVCR can be configured to scan the network for other DVCR units. A list of discovered DVCRs is displayed. Each DVCR can access, after authentication, any of the listed DVCR for configuration, monitoring, controlling, recording, playback and other available functionality over the network. The same controls used for operating a local DVCR, including use of buttons, can be employed to operate the remote DVCR, giving a virtual presence at the remote location. The functionality exhibited by each of the DVCR, can be identical. A plurality of the DVCR can thus form a decentralized, symmetric network in which there is no master or central controller.
摘要翻译：本发明描述了用于通过网络监视，控制，分析，记录，回放和流式传输音频/视频（A / V）媒体的数字录像机（DVCR）的分散对称配置。每个DVCR是能够在其本地环境中操作以及访问和操作网络上可用的另一个DVCR的自主设备，以便于所公开系统的整体工作。每个DVCR还展示存储故障安全功能，如果存储介质由于突然的电源故障而被破坏，它将自动恢复数据。 DVCR可以配置为扫描其他DVCR设备的网络。显示已发现的DVCR列表。每个DVCR在认证之后可以通过网络访问列出的所有DVCR以进行配置，监视，控制，记录，播放和其他可用功能。用于操作本地DVCR的相同控件（包括使用按钮）可用于操作远程DVCR，从而在远程位置提供虚拟存在。 DVCR中的每个显示的功能可以相同。因此，多个DVCR可以形成分散的对称网络，其中不存在主控制器或中央控制器。
